BACKGROUND

1. Field

The present disclosure generally relates to safety eyewear frames and lenses. More particularly, the present disclosure relates to a safety eyewear assembly that includes a prescription insert.

2. Description of the Related Art

Safety eyewear is worn for a variety of safety reasons. As a result, a variety of safety eyewear types, each specifically designed and intended for a particular use or a particular environment, has been developed. For example, safety eyewear is often worn to protect a wearer's eyes from debris during metal machining operations, military operations, and the like. In such an environment, metal shards, sand or other debris may be propelled towards an operator's eyes. Safety eyewear is also worn in the chemical industries to protect employees from airborne chemicals resulting from splashes or spills. Still further safety eyewear is worn in industries utilizing lasers. Lasers can be damaging to the eye if exposed. Lasers are particularly dangerous because different wavelengths of laser light may require different lenses for filtering the damaging light.

Because of the proliferation of safety requirements now requiring greater numbers of employees to wear safety eyewear, cost, ease of replacement of the lenses, the ability to accommodate prescription lenses, and fashion have now become prime concerns for customers of these safety products.

DETAILED DESCRIPTION

Referring now to the Figures for the purpose of illustration, it is to be understood that standard components or features that are within the purview of an artisan of ordinary skill and do not contribute to the understanding of the various exemplary embodiments are omitted from the Figures to enhance clarity.

FIG. 1 illustrates an exemplary safety eyewear 10 that includes a removable lens carrier 12, a lens 14, a frame 16, and a removable prescription insert 18. The removable lens carrier 12 is removably attached to the frame 16 and the removable prescription insert 18 is also removably attached to the frame 16. The safety eyewear 10 can also include a strap 20 is used to secure the safety eyewear 10 to the user.

In one embodiment, the frame 16 is made of a semi-flexible material, which provides a connection point for removable lens carrier 12. The frame 16 and the removable lens carrier 12 may connect to one another using a variety of attachment mechanisms including, but not limited to, a tongue and groove junction, a male and female flange connection, a latch, or the like. In one embodiment, the frame 16 and the removable lens carrier 12 may form an airtight seal. The frame 16 may also include a face seal gasket 22 that provides a seal between the frame 16 and the users face. The removable prescription inset 18 may be attached to or detached from the frame 16 when the removable lens carrier 12 is not attached to the frame 16.

The removable lens carrier 12 is removably attached to the frame 16 and permanently attached to the lens 14. The lens 14 may be provided with a variety of tints and coatings. The removable lens carrier 12 and the lens 14 may have a variety of shapes and sizes that are each specifically designed and intended for a particular use or a particular environment. The removable lens carrier 12 is designed such that a user may detach it from the frame 16 while the user is wearing the frame 16. For example, a user may be able to change the type of lens used without having to completely remove the safety eyewear 10. The removable lens carrier 12 allows the user to use a single safety eyewear in a variety of different environments and for a variety of different uses.

In exemplary embodiments, the removable lens carrier 12 may completely encase the lens 14 or may only partially encase the lens 14. In one embodiment, the removable lens carrier 12 may not cover, or attach to, a bottom portion of the lens 14, which may increases the available viewing angle to the user. For example, traditional safety goggles include a thick frame on the bottom portion of the safety goggles that may obstruct the user's field of vision. The use of a removable lens carrier 12 that does not cover, or is attached to, the bottom portion of the lens 14 provides the user with an unobstructed field of vision. Additionally, the frame 16 may also have a reduced thickness on the bottom portion of the safety eyewear 10 to provide an increased field of vision to the user.

Referring now to FIG. 2, another exemplary safety eyewear 100 that includes a removable lens carrier 112, a lens 114, and a frame 116 is illustrated. The safety eyewear 100 is designed to provide an unobstructed field of vision to its user. Accordingly, the frame 116 extends from a lower portion of one side of the safety eyewear 100 across the top of the safety eyewear 100 to the lower portion of the opposite side of the safety eyewear 100. In addition the removable lens carrier 112 only covers the sides and upper portion of the lens 114 thereby providing the user with an unobstructed field of vision.

Referring now to FIG. 3, another exemplary safety eyewear 200 that includes a removable lens carrier 212, a frame 216, and a removable prescription insert 218 is illustrated. In one embodiment, the removable prescription insert 218 and a frame 216 are designed to securely connect to each other such that the removable prescription insert 218 remains properly positioned and connected to the frame 216 during the use of the safety eyewear 210. In one embodiment, the removable prescription insert 218 is attached to the frame 216 by pinching a nose portion of the frame 216. The removable prescription insert 218 may include a single lens or two lenses connected by a wire. The wire may be used to attach the removable prescription insert 218 to the frame. For example, the wire may pinch the nose portion of the frame 216 and/or may include an attachment portion, which may be inserted into a receptacle on the frame 216. The frame 216 may be designed to accommodate a variety of different shaped removable prescription inserts 218.

In one embodiment, the safety eyewear 200 may also include a strap 220 and a strap attachment device 226. The strap 220 may be adjustable in length and may be made of an elastic material. The strap 220 may be permanently or removably attached to the frame 216 by the attachment device 226. The attachment device 226 may include a variety of different devices. For example the attachment device 226 may be a loop extending from either side of the frame 216 and the strap may include a hook, hook and loop fastener, a buckle, or any other means for securing the strap 220 to the attachment device 226. In another example, the attachment device 226 may be a button that attaches the strap 220 to the frame 216.

In one embodiment, the attachment device 226 may be a flexible cable that is anchored in the frame 216. In one embodiment, the flexible cable may extend the entire length of the frame 216 and may provide structural support to the frame 216. The flexible cable provides a flexible attachment device 226 that allows the point of attachment between the frame 216 and the strap 220 to be adjusted to accommodate varying uses of the safety eyewear 200. The flexible cable may be in the shape of loop and permit a wide range of attachment angles for the strap 220. In one example, the safety eyewear 200 may be worn with a helmet and the flexible cable allows the user to selectively wear the strap 220 either above or below the surface of the helmet. In an alternative embodiment, the strap 220 may connect the frame 216 to a helmet worn by a user rather than connecting the two ends of the frame 216.

In an exemplary embodiment, the flexible cable is attached at a lower first side frame portion, extends as a loop to the upper first side frame portion, is routed through an aperture in an upper frame portion between said first and said second sides, extends as a loop from the upper second side frame portion and is attached at a lower second side frame portion. The term loop is intended to encompass any geometry configuration of the cable, as long as the cable extends away from a lower side frame portion and an upper side frame portion to a strap attached thereto. The term loop is also intended to cover a scenario wherein the cable is fixedly attached to, e.g., a strap adapter.
